EDDL Waypoints for ILS23L/ILS23R approaches with DUS transition have wrong coordinates

Navigation Data General non MSFS data

Hi,

the XML files for the EDDL procedures in the LevelD dataset
seems to have an error in the coordinates of the D11.6 DUS waypoint for the ILS23L and ILS23R approaches.
They are the same as the IAF waypoint (which is the airport itself), which leads to unusable routing in the navigation display and autopilot.

Kind regards

Hi,
Which sim and which addon do you use?

Cheers

The leg is an “FD” leg, course from a fix to a DME distance. The leg’s termination is not defined by latitude/longitude coordinates, there is a starting point (DUS VOR, along with latitude/longitude for the starting point), a course to follow, and a DME distance to stop after.

The leg’s termination is constructed by the FMS from the starting point, the course and the DME distance; there are no latitude/longitude coordinates for it in the data. If your FMS is not drawing the procedure properly, it might just be interpreting the data incorrectly.

        <AppTr_Waypoint ID="2">
          <Name>DUS</Name>
          <Type>DmeIntc</Type>
          <Latitude>51.283189</Latitude>           <--- latitude  of DUS VOR (starting point)
          <Longitude>6.753725</Longitude>          <--- longitude of DUS VOR (starting point)
          <Speed>0</Speed>
          <Altitude>3000</Altitude>
          <AltitudeCons>0</AltitudeCons>
          <AltitudeRestriction>above</AltitudeRestriction>
          <Hdg_Crs>0</Hdg_Crs>
          <Hdg_Crs_value>033</Hdg_Crs_value>       <--- magnetic course to follow from DUS VOR
          <Flytype>Fly-by</Flytype>
          <BankLimit>25</BankLimit>
          <DMEtoIntercept>12.0</DMEtoIntercept>    <--- how far to "travel" on above course
          <Sp_Turn>Auto</Sp_Turn>
        </AppTr_Waypoint>

I do find it a little odd that the DME distance is 12.0 where it’s 11.7 on the charts and in other data sets that I checked, but this could potentially just be due to the way I had to extract the data, being away from home and not having access to a Windows machine?

Ah, my mistake. I’m using FlightGear, seems the A320 has a problem with DmeIntc waypoints.
Thanks for the quick reply!
